Abstract: A method for detecting abnormal behavior involves constructing words and text documents based on data acquired from mobile phone sensors during defined time intervals. The time intervals are defined based on data from mobile phone sensors indicative of usage patterns of the mobile phone user. Words are constructed for each time interval as a vector including the time interval and sensor-based feature levels. Each sensor-based feature level is mapped to a range of values of a sensor-based feature that are extracted from the sensor data. The text document is constructed from the words based on the time intervals and the sensor-based feature levels. A current routine for each time interval is determined using topic modeling based on the words that most frequently appear in the text document. An alert is generated if the current routine for any time interval deviates from a past routine for a corresponding past time interval.

Abstract: A preventative healthcare system calibrates a risk model by assigning weights to attributes for the freshness, completeness and uncertainty of a user's medical information. A risk predictive model is implemented based on the medical information. The risk of a specific health outcome of the user is determined using the risk predictive model, which is calibrated by computing attribute scores for freshness, completeness and uncertainty of the medical information and by assigning weights to the attribute scores. A need-for-data (ND) score is computed using the weighted attribute scores. A need-for-checkup (NC) score is computed using traits of the user. The method determines that new medical information related to the user is needed or that the user needs a checkup based on the ND and NC scores. A prompt is delivered to the user indicating that new medical information related to the user is needed or that the user needs a checkup.

Abstract: Method, system and computer program for determining personalized parameters for a user. The method comprises providing a first vector of personal characteristics based on received first data, a second vector of behavior and activity characteristics based on received second data, and a third vector of wellbeing measures based on received third data. Exhibited personal characteristics and the first vector is also calculated. A reference group for the user is created and a similarity measure between the user and the reference group is implemented to identify which of said users has more characteristics in common with the user. An optimal behavior and activity distribution vector can be determined from the most similar users of said reference group. The range of behaviors and activities that are good or bad for the user can be also determined.
